Map protein names, synonyms, and UniProt identifiers to STRING identifiers. Species parameter uses NCBI taxon IDs (e.g., 9606 for human, 10090 for mouse).
AI agents call get_string_ids to retrieve information from STRING MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward lookup/query operation that retrieves protein identifier mappings from the STRING database. It has no side effects—it only reads and returns existing data in a different identifier format. No data is created, modified, deleted, or financial obligations incurred. The blast radius of misuse is minimal since the tool cannot alter any data or trigger external operations.
From the tool's definition Tool maps/resolves protein identifiers to STRING IDs with no modification capability. Description states it enables 'mapping identifiers' and 'retrieving' data, with no language indicating data creation, modification, deletion, or external state changes.
Attacks that exploit this kind of access
Map protein names, synonyms, and UniProt identifiers to STRING identifiers. Species parameter uses NCBI taxon IDs (e.g., 9606 for human, 10090 for mouse). It is categorised as a Read tool in the STRING MCP Server MCP Server, which means it retrieves data without modifying state.
Register the STRING MCP Server MCP server in PolicyLayer and add a rule for get_string_ids: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches STRING MCP Server. Nothing to install.
get_string_ids is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_string_ids rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_string_ids. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_string_ids is provided by the STRING MCP Server MCP server (munch-group/string-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Every MCP server has a record like this.
